    摘要:
    浙江某工业废水处置厂进级革新,采取AAO—MBBR复合生物膜工艺,在未新增扶植用地和扩建池容的根本上,日处置量由3×104m3/d提高至6×104m3/d。革新后现实运转出水COD、TP、NH3-N和TN浓度别离为(37.7±6.61)、(0.09±0.03)、(0.25±0.14)和(5.87±1.54) mg/L,出水水质不变到达一级A尺度。现实监测注解,在好氧MBBR区具有TN去除现象,约占TN总去除量的10.36%。系统内的劣势硝化菌属为硝化螺旋菌属Nitrospira,其在悬浮载体生物膜和活性污泥中的相对品貌别离为8.98%和0.92%,悬浮载体的投加使硝化细菌获得有用富集;反硝化菌在生物膜中的占比为7.94%,为悬浮载体同步硝化反硝化(SND)结果的产生供给了微不雅包管,提高了TN去除率。
    Abstract:
    An industrial wastewater treatment plant in Zhejiang was upgraded by a combined process consisting of anaerobic/anoxic/oxic activated sludge process and moving bed biofilm reactor (AAO-MBBR). Without changing the footprint and increasing the reactor volume, the treatment capacity increased from 30 000 m3/d to 60 000 m3/d after retrofitting. Concentrations of COD, TP, NH3-N and TN in effluent were (37.7±6.61) mg/L, (0.09±0.03) mg/L, (0.25±0.14) mg/L and (5.87±1.54) mg/L, respectively, which met the first class A standard. Actual operation data indicated that TN removal existed in the aerobic MBBR zone (accounting for 10.36% of total TN removal). Nitrospira was the dominant nitrifying bacteria in the system, and its relative abundance in the suspended carrier and activated sludge was 8.98% and 0.92%, respectively, indicating that the addition of suspe����APPnded carrier could effectively enrich the nitrifying bacteria. The proportion of denitrifying bacteria on biofilm was 7.94%, which created a microenvironment for the occurrence of simultaneous nitrification and denitrification (SND) in the suspended carrier and improved the TN removal efficiency.
